DIY triple monitor stand plus second tier (4 monitors total)

So there are plenty of threads about making your own tripple monitor stand, and a few people have talked about making it two tiered to fit 4-6 monitors. I just finished making a 4 monitor versions, so here are some pics of what I did. This isn't meant to be a guide, just proof that this can be done, plus a few helpful pointers for those interested in doing something like this.

I started with the basic frame work seen here, but I wanted to expand it to fit 4 monitors. To do this is swapped the T junction for an X junction. The forth monitor will mount off of a 12" pipe, straight over the primary display. Here's a pic:



I made my own VESA mounts using the template from the previously mentioned thread, but I exaggerated their size by making them 6x6 instead of 5x5. This gave me more wiggle room if something went wrong. Here's a pic of that:



At this point I ran into some trouble that I (foolishly) did not expect. The X connection meant that the primary monitor didn't sit flush with the wood mounts, while the other monitor did. This means it stuck out about 1/4" when I tried to mount the side monitors. My solution was to put some metal spacers under the pipe straps of the side monitors. I used what I had on me, in this case, pennies. Pro tip: glue the pennies together before trying to slide them under the pipe. Here's a picture of that:



I next I bolted these bad boys to my desk, and that was that. Here's a picture of the back of the setup with all the monitors attached, and attached to my desk.



Here's a picture from the front with all the monitor up and running.



A FEW FINAL THOUGHTS:

All together this took 5 hours, and $90 at home depot. I had to buy a pipe wrench and I didn't have any spare wood around. If you have all the tools and some spare wood, you could do this for $70, maybe less if your homedepot is cheaper than mine.

When you mount the monitors to the pipe, keep their bases on. This makes is way easier to level and tighten. I didn't tighten down my left monitor enough before removing the base, and trying to adjust it without its base was a serious pain.

I used 90 degree to a 90 degree street to connect my arms. This is completely because that's what homedepot had. I wanted to use 45's.

Thanks to eovnu87435ds and seven9st for the inspiration.

Exactly. The only flaw is that the side monitors are about 3" below the primary. Not a big deal, but it means I had to measure the side mounts separately. I couldn't just make 3 identical mounts and expect those to work.

Less than when they were all on their default bases. They also don't respond to desk movement. Used to, if I bumped the desk, they would rock. Not anymore. They have an auto on/off feature (pretty common now), so I don't ever have to touch them.
